Tips

Don’t clump up, because more targets hit by her ultimate will give her a bigger shield.

Try to place Vision Wards in typical ganking paths such as River/Tribrushes so that you can see her coming.

If laning against an Evelynn, let your team know everytime she is missing even if you’re unsure if she’s just stealthed or not.

Evelynn is difficult to keep track of if you ward in the usual locations. Try to put wards near her jungle camps to keep track of her. When she goes to clear that camp she will be visible while attacking. Also, pink wards. Get everyone to buy them.
